Medical testing firm Omega Diagnostics is forecasting revenues of more than £11 million for the 2011 year, up 41 per cent on the previous year.

Omega, which develops food allergy testing kits, said the bulk of the gains have come from its acquisition of the German lab testing firm Allergopharma in November 2010.

Germany is now Omega's largest market, and stripping out the gains from the Allergopharma business, revenues on a like-for-like basis for the year are expected to be up five per cent on the previous year.

Revenues from the Allergopharma business are expected to be up more than 300 per cent on the previous year at £3.87 million.

Sales of Omega's food intolerance testing kits are also expected to be up 10 per cent on a year ago to around £3.9 million.

Omega chief executive Andrew Shepherd said: "We are very pleased with the progress Omega has made and the overall business is performing strongly.

“We are also looking forward to significant opportunities presented by direct access into the Indian market, the launch of a range of allergy tests onto the automated IDS-iSYS platform (allergen testing) and new prospects that exist that could transform the performance within our Infectious Disease portfolio."

Omega Diagnostics specialises in developing food intolerance testing kits as well as tests for infectious and auto-immune diseases and now operates in 100 countries.

The company historically focused on selling testing kits into the developing markets for diseases such as tuberculosis and Dengue fever but moved into food testing after its 2007 takeover of Cambridgeshire-based Genesis Diagnostics.
